Um caso de dermatose perfurante adquirida

We present a case of acquired perforating dermatosis (also known as acquired perforating collagenosis) which is frequently associated with diabetes mellitus and chronic renal failure. A 61 year old diabetic woman had a history of umbilicated, pruritic papules and nodules, with a central keratotic plug, located on the extensor surface of the lower limbs. The diagnosis of acquired perforating dermatosis was made six years after the initial clinical presentation. This article seeks to alert physicians to the existence of this under-diagnosed condition with considerable psychosocial impact.
